Application filed January 14, 1909. Serial No. 472,184.

T all whom it may concern:

Be it known that I, VICTOR ZDZIARSKI, a subject of the Czar of Russia, and residing at New York, in the county of New York and .5 State of New York, have invented certain new and useful Improvements in Running- Gear Mechanism and Brake Apparatus for T ramway-Cars, of which the following is a specification, such as will enable those skilled 0 in the art to which it appertains to make and use the same.

This invention relates to tramway cars; and the object thereof is to provide an improved running gear mechanism and brake apparatus for cars of this class, the construction being such that the brake apparatus may be operated from either end of the car and the car conveniently and easily turned on curved tracks without interfering with the 0 operation of the brake apparatus, and with this and-other obj ccts in view the invention consists of the construction, combination and arrangement of parts hereinafter described and claimed.

5 The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in 0 each of the views, and in which Figure 1 is a bottom plan view of the bedwork or frame of a car body and showing my improved running gear mechanism and brake apparatus, all the super-structure of 5 the car being omitted, Fig. 2 a side view thereof partly in section on line 22 of Fig. 1, Fig. 3 a section on either of the lines 3-3 of Fig. 1, or on either of the lines 3'3 of Fig. 2 and with parts broken away, Fig. 41 a View similar to Fig. 1, but showing the position of the running gear including the truck frames when the car is turning a curve, the truck frame, wheels, axles and parts connected therewith being shown diagrammatic only, Fig. 5 a view similar to Fig. 1, but showing the brake apparatus in operation and showing only a part of the construction, and ;-Fig. 6 a side view of a modified form of brake head or block which I employ.

0 In the drawings forming part of this specification, I have shown at a the bed-work, *frame or bottom of a car, the ends a of which form the platforms of the car, and in the practice of my invention, I provide, in

5 the form of construction shown, two truck frames 1), said truck frames being rectangular in form and composed of parallel side members and parallel outer and inner members I), and the parallel outer and inner members I) are preferably composed of angle iron.

The side members b of the truck frames I) carry and form part of the journal boxes I) in which the ends of the axles b are mounted in the usual manner, and said axles are provided with the usual wheels I).

The bed-work frame or bottom a of the car is supported on the truck frames 1) by spider-work. devices 5 comprising central portions b and legs or arms I) connected with the parallel inner and outer members I) of the truck frames, and the connection of the central portions b of the spider-work devices with the bottom or bed-work a of the car are pivotal connections made by means of king pins 0 which pass through wear plates 0 secured to the bottom a of the car, or this connection may be made in the usual or any desired manner.

The truck frames 1) are provided at their corners with cup-shaped receivers c in which are placed conical spiral springs c in the tops of which are placed or secured pins or plugs 0 provided with roller heads a which bear on plates 0 secured to the bottom a of the car or truck frame, and loosely connected with the inner sides If of the truck frames 1) by means of links d are cross bars (1 with which are pivo tally connected diagonally arranged and interacting link bars (1 This construction, as will be seen, constitutes the running gear of the car, and by means thereof the truck frames 1), the axles I)" mounted therein and the wheels 7) are free to follow the rails of the track and to turn on curves thereof as indicated in Fig. 4, and this construction also renders unnecessary the use of four wheel trucks, or what are known as two wheel trucks with trailers as the following truck is always compelled to turn in a direction opposite to that of the preceding truck as indicated in Fig. 4 and to follow said preceding truck on a curve, this operation resulting from the intermediate connection of said trucks comprising the parts (Z, d and (Z Between the truck frames 1) and suspended from the bottom bed-work or frame of the car are parallel yoke shaped hangers (1* which are directly over the cross bars d when the latter are in their normal or parallel position as shown in Fig. 1, and said cross bars are provided with segmental slots (Z through which are assed pins or bolts (Z secured in the yoke-s aped hangers (i The construction hereinbefore described covers the running gear inde endent of the brake mechanism which wil now be de scribed. Mounted transversely of and over the truck frames b are draw bars 6 provided in their opposite end portions with longitudinal slots e through which are passed pins or bolts 6 secured in the inner and outer par allel members b of the truck frames 6, and the draw bars 6 are also provided at their outer ends with transverse and segmentally curved link-shaped heads 6.

Below the opposite end latforms (L2 of the bottom a of the car are yoke-shaped hangers e in the bottom portions of which are pivoted as shown at e levers 6 having segmentally curved portions 6 at their lower ends and handle portions (2 which pass up through slots f in the platforms a and the curved portions 6 of the levers e are provided with segmental slots f Connected with the heads 6 of the draw bars e are yoke-shaped devices f this con nection being made by means of pins or bolts f 5 passed through the slots in the heads 6 of said braw bars, and the yoke-shaped devices f are provided with slots in their outer ends and through which the levers 6 pass, and pins f are passed through said yoke-sha ed devices and through the slots f 2 in the evers 0 Connected with the inner ends of the draw bars e are link devices 9 which are connected with a central supplemental link device g which is pivoted to a central yoke-shaped hanger g secured to the bottom end of the car.

The axles b are each provided on the inner sides of the wheels I) with longitudinal lugs or short ribs h, and loosely mounted on said axles are two lock or brake heads and blocks 2 having backwardly directed arms 77 provided at their rear ends with vertically arranged yokes t in which are placed bolts 71 which pass downwardly through the inner portions 6 of the truck frames 1) and on which and above and below said inner portions of the truck frames are placed springs F.

The lock or brake heads 1' are also provided with outwardly directed members or projections i with which are connected links j, said links being pivotally connected by bolts which are secured in the draw bars 6 rearwardly of the outer parts of the truck frames Z), and the lower ends of said bolts are supported by braces j secured to the draw bars 6 at 3' and the bolts j are provided above and below the links with springs The lock or brake heads 1' are provided with openings m through which the axles 6 pass, and these openings are enlarged and seml circular in form at one side as shown at m and this forms shoulders m above and below the axles, and when the lock or brake heads 71 are moved outwardly in the operation of the brake apparatus the lugs or short ribs 72. on the axles pass through the openings 17?. and as the axles turn said lugs or ribs come in connection with the shoulders m and the rotation of the axles and wheels is stopped as will be readily understood. This operation will, of course, cause a sudden jerk or jar, and the shock thereof is taken up by the springs i and which permit of a slight vertical movement or rotation of the lock or brake heads 111 Fig. 1, the parts are all shown in their normal position with the brake apparatus out of operation, but in Fig. 5 the brake apparatus is indicated in operation In order to throw the brake apparatus into operation the lever e at either end of the car may be operated, and in this operation said lever is forced inwardly as indicated in dotted lines. This forces the lock or brake heads i as inclicated in Fig. 5 and the wheels and axles are locked, and in order to release the said wheels or axles the lever is moved back into its normal position as indicated in Fig. 2.

Only a part of the brake apparatus is shown in Fig. 5, but enough is shown to indicate the operation thereof and the position which the main parts thereof assume when in operation; and in Fig. 4 thetruck frames 1), the axles and all the interior parts of said truck frames are indicated diagrammatically only, the showing of the details in this figure being deemed unnecessary.

In Fig. 6, 1 have shown a modification of the brake heads or blocks i in which the central opening through which the axles 6 pass is circular in form and provided at approximately opposite sides with inwardly directed lugs or projections 0 forming two openings 0 and 0 through which the lugs or ribs h on the axles b may pass, and with this construction the said lugs or ribs h operate in connection with and on either side of the lugs or projections 0 as will be readily understood.

From the description, it will be seen, that the operation of the brake apparatus is independent of the particular form of running gear shown and described except that portion of the running gear consisting of the truck frames 1) and those parts of the brake apparatus that are connected therewith; and various changes in and modifications of the running gear and other parts of the mechanism herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what 1 claim as new and desire to secure by Letters.
